533x1981x35mm (21") Heritage Black Primed Clear Glazed Internal Doors

It builds on the runaway success of our external Black Heritage French Doors, which took their cues from the traditional Crittall style with slim stiles and rails, and translates that same look for use inside the home.

Built on an engineered core with a smooth primed surface, these Heritage Black Clear Glazed Internal Doors are made for urban, industrial-inspired spaces. They come into their own against exposed brickwork or off-white walls, where the door stops being a background detail and becomes a defining feature of the room. There's a practical advantage too: despite a stile width of just 70mm, the door accepts a conventional 65mm or 75mm latch set, sparing you the considerable added expense of specialist shallow backset latches that comparable doors typically require. The primed surface simply needs a top-coat on site, in black or any colour you prefer.

Glazed with 4mm toughened clear safety glass as standard and covered by a guarantee against manufacturing defects, these 35mm thick doors come in a selection of traditional imperial sizes. Each is finished with 10mm lippings on all four edges, allowing up to 6mm to be trimmed from any edge (a maximum reduction of 12mm in width or height).
